Growth in the sea comes down to a struggle for iron

... had already injected iron into the water and were monitoring the growing phytoplankton patch, roughly six by eight kilometers in size. "The patch changed quickly and constantly, breaking into two patches and streaming out into a long, narrow strip. The major night-time task was to steam in crisscrossing trans...

UCLA Study Shows One-Third of Drug Ads in Medical Journals Do Not Contain References Supporting Medical Claims

...anies," Cooper said. Schriger noted that improved monitoring and access to references in pharmaceutical ads may be helpful to physicians and policy makers in making more informed prescribing decisions. According to the authors, the Federal Drug Administration screens the drug ads for validity, but the sheer v...

First real-time view of developing neurons reveals surprises, say Stanford researchers

... one in real time. The technical savvy involved in monitoring neurons will allow researchers to conduct experiments that were previously not possible. While the research showed neurons firing in a more mature way than expected, it also revealed that neurons take their time establishing the final wiring of the ...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...e emerging field of molecular therapeutics and for monitoring the delivery of therapeutic genes in patients. "For 20 years it has been the chemist's job to develop agents that can be used to enhance MRI contrast," said Eric Ahrens, assistant professor of biological sciences in the Mellon College of Science at ...

Artifical cornea lets woman blind 20 years see

...t Duke University Eye Center and Harvard have been monitoring her closely following the implantation of an artificial cornea, or keratoprosthesis, into one of her eyes -- restoring her sight in that eye and ultimately helping her regain much of her independence. Phifer is one of several hundred patients nationw...

Pathogen-Mimicking Vaccine As Strategy For Cancer Therapy

...ed because we are using reproducible immunological monitoring across the CVC, allowing a more accurate comparison of the effects of CpG 7909 in this trial with the results of several other adjuvants that have been tested in other trials. By comparing single variables in parallel we believe we can develop effect...

Use of PET can reduce, may eliminate more strenuous drug development trials with animals

...es the chemistry and biology of a person's body by monitoring ingested tracer molecules, and it is used to study the metabolism of the brain, the heart and cancer. A miniature version of PET was developed and is used in much the same way to image small animals. Small animals, especially mice, play a fundamenta...

WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas

...increased risk of Dengue in Aceh and are carefully monitoring the situation. Concerns for malaria remain high, too. Although there is no information to suggest an increase in malaria cases in Banda Aceh, the area is endemic for the disease. "At present, we are dealing with a lot of unknowns because of the viole...

Chemicals in tattoo inks need closer scrutiny

...of toxic metals will encourage regulators to begin monitoring the tattoo ink industry more closely. There are other problems with unknown compositions of tattoo inks. For example, surgery to remove tattoos is becoming more widespread, and not knowing the composition makes the procedure more difficult. "Once th...

Live vaccines more effective against horse herpes virus

...administers testing and does not set the rules for monitoring infections. Dubovi said that in the last four to five years, there have been more reports of the severe neurological disorder associated with equine herpes. "It appears we are seeing it with more frequency and in a larger number of horses," he said....

Scientists journey to southern Africa to unravel the secret world of elephant communication

...er and Colleen Kinzley acted as "blind observers," monitoring the herds but never knowing which recordings, if any, were being played back through the shaker. Their observations would provide an unbiased assessment of the elephants' behavior. Although still analyzing data from the 2004 experiment, O'Connell-Ro...

Elephant seal pups suffer from ocean warming

...nclude the authors. Le Boeuf and Crocker add that monitoring the mean weaning weight of elephant seal pups can therefore help track changes in ocean temperature cycles. ### This press release is based on the article: Ocean climate and seal condition Burney J Le Boeuf, Daniel E Crocker BMC Biology 2005, 3:9 ...

Measuring Enzymes At End Of Cancer Pathway Predicts Outcome Of Tarceva, Taxol

...d the expression, simultaneously. They found that monitoring of two isotypes of CDK activity accurately predicted which tumors would respond to Taxol in the experiments with human breast cancer cell lines and tumor tissues of human xenograft model. "This provides solid preclinical evidence that we can use tow...

Conserved amino acids play both structural and mechanistic roles in sandwich-like protein

...ing a nonessential amino acid for each of them and monitoring the effect on the protein structure. (For technical reasons, the other two amino acids could not be studied.) The researchers found that three of the amino acids are important for stabilizing the final structure of the protein, and three serve to dir...
